Florence-based Leisure Excavating, working with state park staff, buried the 55-foot long, 30-ton carcass above the high tide line at the park in an 11-foot deep hole. The corpse will decompose naturally, officials said.

Oregon Parks & Recreation said the park will return to normal operating hours today, and be open from 7 a.m. to dusk. The viewpoint and Devil’s Elbow Beach north of Florence were closed on Sunday due to concerns for traffic safety and protection of the carcass.

Marine Mammal Stranding Network biologist Jim Rice completed his work to attempt to determine the cause of death (a necropsy), but has not yet released any findings. The true cause may remain a mystery.

The Oregon Parks and Recreation Department's Whale Watching week arrives during spring break, from March 21-28. Volunteers will staff 26 watching stations from 10 a.m. - 1 p.m. each day. Gray whales are the species seen most often.
